摘要

A method for removing juvenile angiofibroma of the skull base, localized in the nasal cavity, nasopharynx, sphenoid sinus, the pterygopalatine fossa and reaching infratemporal fossa comprising transnasal endoscopic access execution antrostomii to remove the tumor from the pterygopalatine fossa, characterized in that the tumor is removed from the nasal cavity tsentripetalno partial resection of the lower edge of the middle turbinate, opening the medial wall of the maxillary sinus on the natural anastomosis when expressed distributing tumors in pterygopalatine and infratemporal fossa and with a slight spreading of the tumor in the pterygopalatine fossa antrostomiyu operate at the rear end of the middle turbinate, wherein from the lumen of tumor removal sphenoid sinus is performed by direct transnasal access with resection of the upper nasal turbinate and removal of the front sinus wall through bone vykusyvateley , separation of the tumor located in the lateral parts of the nasopharynx and the opposite side from the rear parts of the nasal septum, carried biportalno tsentripetalno through both halves of the nose, keeping the back of the nasal septum.
